PAPER-TUBE-ROLLING ItIACHINE.

Specification of Letters Patent.

Patented Aug. 111, 1244.

. Application filed May 25 1911. Serial No. 629,444.

@ sia, Germany, a subject of the Emperor of Germany, have invented new and useful Improvements in Paper-Tube-Rolling Machines, of which the following is a specification.

My invention relates to an improved machine by which paper tubesare rolled and pasted, and it consists'in the combination of means by which the blank is cut off from a roll, then adjusted in an exact position,

then seized by a nipper and inserted axially in a slot forming roller whereby it is rolled up, and during'this operation glue is fed by a brush to the tube, another brush smoothing its surface and a finishedtube being then pushed out of the machine.

With these and other objects in view my machine is illustrated on the accompanying drawings and described in the following specification.

Figure 1 is a top view of the complete machine with the glue applying rollers.11 removed. Fig. 2 is a front elevation of the complete machine. Fig. 3 is a cross section taken in the direction of line 11 of Fig. 1 on an enlarged scale. Fig. 4 is a top view of a part .of Fig. 1 on an enlarged scale. Fig.5 is a detail view in elevation of the paper clamp and the tube remover. Fig. 6 is a vertical section On the line 4-4, of Fig. 1. Fig. 7 isa vertical section taken on line 2-2 of Fi 1. Fig. 8 is a vertical sec-,-

tion taken on ine 3--3 of Fig. 1. Fig. 9 discloses a view of the gears 41 and 42, and Fig. 10 discloses an end elevation of the forming roller. d

Like letters of reference indicate like parts in the drawings.

On the bed plate a of the machine is journaled a shaft 1, rotated by the pulley 4 which may be driven and arranged totransmit power in any proper known manner, the.

rotation of shaft l-transmitting motion by means of the bevel gear 2 to a shaft 3, which ,by means of the gears 6, 7, 7, 7, 7 8 and .8

rotates the rollers 9, between which is guided the paper 10 having previously passed over a glue feeding device 11 of known construction. It follows that the paper then passes between another pair of rollers 12 which guide the'paper in to the cutting device 13,- said device consisting of two knives, one of paper is first clamped down on the table of the machine by the bearing surface 18 of a lever 17 which is operated upon by a cam 16 of shaft 3 andra blank of the desired length is cut from the paper by the said knives 13. ()n the table is arranged the slide 19 which is secured to a bar 21, which is inengagement with-a cam 20 of shaft 3, said slide in operation, shifts the blank laterally with its longitudinal edge against a rigid member 22, thereby securing its proper position relative to the forming roller 24 onto which the blank will be delivered. 1 This work is mechanically carried out by means of a scissors-like tool or nipper 23, said nipper consisting of a member 25 and a cooperating member 26 shown by Fig. 5, and is reciprocated by means of the link 27, levers 28 and 29, crank 29, disk 30, gear wheels 31' and 31, and shaft 1, the said member having a bearing 25 which slides along a shaft 25. The members 25 and 26 which are closed by a spring 32 are opened by means of a lever 33 which engages the projection 34 of the nipper, when the latter is in its farthest leftward position. The'lever 33 is actuated by a cam disk 35 seated on shaft 1. The nipper members 25 and 26 are held in ,the open positionby a spring actuated arm 36 until they seize the blank engaging for this purpose a protuberance 37 on the projection 34, as shown in Fig.5. In the right moment, the nipper having received the blank bet-ween its jaws, the arm 36 will be released by moving into contact with a rigid bolt 38, and the blank is clamped by said nippers, and can now be, inserted thereby/into the longitudinal slot 24 of the forming roller 24, which is rotated intermittently, so that the slot will aline with an edge of the paper and guide-bar, for receiving the paper. For

momentarily interruptedwhich is effected by means of ordinary quadrant gear 39 mounted on shaft 3, which is in mesh with the gear train 40, 41 and 42, which is arranged for increasing the angular velocity of the forming roller 24; .Journaled in suitable bearings is a shaft 43 which is revolved from .shaft 3 by 'means of gears 44;, 45, 46, which shaft is fitted with two brushes 47 and 48. The shaft 49 is provided with a spoon like plate 50 that is rocked by a cam 51of shaft 3, which plate takes glue from a rewhich is alternately raised and lowered by means of'a cam 14 keyed to shaft 3. The

this purpose the rotation of said shaft is ceptacle 52, applies said glue to the brushes 47 and 48, which apply the glue on to the blank. The superfluous fluid will be removed by a sheet metal plate 53, carried by two arms 54 which are pivotally mounted on [shaft 49, and are caused to oscillate by means of a roller 55 and the cam 56 on shaft 3, the roller 55 being carried by a shaft 55' journaled in the arms 54:. It will be understood that in this manner the glue is removed and also the paper of the roll is pressed down and made smooth, for which latter purpose the brush is also of effective I use. After the pa er tube has been finished per moves backward, and vice Versa. By

this means the expeller will be moved along the forming roller 24 and cause the tube to be thrown from the roller out of the machine.

What I claim is:

l. The combination in chine, of a bed plate, plate, a guide bar on the table, means for causing a strip of paper to move forward a paper tube maa table over the bed over said table, means for applying glue to one surface of said paper as it moves forward toward the table, means for clamping the paper on the table, means for cutting off a blank from said paper while it is clamped on the table, means for shifting the blank laterally until an edge thereof comes into contact with the guide bar, a slotted forming roller, means for rotating the roller intermittently so that it stops with its slot in alinement with an edge of the guide bar and of the paper, and means for moving the blank forward with an edge thereof in said groove, said roller windingsaid'blank there-- on as it rotates, and means forhapplying glue to the other surface of the paper blank while being wound.

2. The combination in a paper tube machine, of means for cutting a blank from a strip of paper, means for applying glue to said strip before said blank has been cut, a roller having a groove therein, a guide bar, means for shifting the blank laterally with one edge against said guide bar, means for rotating said roller intermittently so that the groove thereof stops in alinement with said edge of the blank, means for grasping said blank and drawing said edge into saidslot, whereupon the rotation of said roller winds the blank thereupon.
